Here are software that related with Samsung B series TVs. Like hex editors, new version of BusyBox or internal software, app programs that will run in your TV hardware.This forum is NOT FOR USER QUESTIONS or Problems.

motocrossmann's:
* app/patch to power off TV at no-signal state, with delay (as I know now it only works for VGA input, not sure about DVI)
(I made some tests with scalers data and I think I can do it in PVR+. In no-signal state bVideoOn is zero)

my ideas:
* an older version of firefox (we need better web browser than Netsurf)
* remote desktop viewer (RDP client)
* live webcam viewer, to view web cameras all over the world on the TV screen; I mean moving pictures, not still images.

- Downmix 5.1 to 2.0 (AC3, AAC or DTS streams). According some other forum, a good formula for ffmpeg is "pan=stereo|FL=FC+0.6FL+0.2BL|FR=FC+0.6FR+0.2BR"
- Detect and switch subtitle streams inside mp4 or mkv
- During playback of a video, show extra information when "info" button pressed like: video codec, audio and subtitle streams

Almost hopeless. Use any patch already available here or try develop yourself. I would not expect any updates for this series. Users who were actively developing for B are retired and rarely seen on forum if at all. Sorry.
